Understand that http health check monitor support is http0.9 by default, please advise which is more recommended http0.9 or http1.1?

thanks for your reply. will you be able to advise on the situation that all along, we were using health monitoring http80, then suddenly this monitoring shows disabled, and we change the health monitoring to tcp, and it shows enabled, and the issue was resolved. Any idea any possible cause?

    If the tcp monitor shows UP and http monitor shows DOWN, there are some possibilities e.g.: HTTP service is absent on tcp port 80, HTTP monitor parameters are incorrect, etc. If you can access the website resources, means that http monitor parameters are probably wrong (e.g. "Receive String") or server responses are intermitent for the requests.
